Question

Quizplus · Accepted Answer

During fluoroscopy, the primary x-ray beam passes through the patient and strikes the input screen of the image intensifier. The input screen is made of a material that converts the x-rays to visible light. The visible light photons are then accelerated and focused by the electrostatic lenses and then strike the photocathode, which emits electrons that are further accelerated and focused by the electrostatic lenses to produce an intensified image on the output screen.
